A plane intersects a rectangular pyramid horizontally as shown. Describe the cross-section.
A) circle
B) rectangle
C) trapezoid
D) triangle
I am sure it is c, but I may be wrong.
I just did it, its B a rectangle.
To determine the cross-section of a plane intersecting a rectangular pyramid horizontally, we need to consider the shape formed by the intersection.
In this case, since the plane is horizontal, the cross-section will be a horizontal slice of the pyramid. If the plane is parallel to the base of the pyramid, the resulting cross-section will be the same shape as the base.
Since the shape of the base of a rectangular pyramid is a rectangle, the cross-section of the plane intersecting the pyramid horizontally will also be a rectangle.
Therefore, the correct answer is B) rectangle.
To determine the shape of the cross-section created by the intersection of a plane and a rectangular pyramid horizontally, we can visualize the scenario.
A rectangular pyramid has a rectangular base and triangular faces that meet at a common vertex, called the apex. When the plane intersects the pyramid horizontally, it means that the plane is parallel to the base of the pyramid.
In this case, the cross-section will be a shape that corresponds to the outline of the base of the pyramid. Since the base of the pyramid is rectangular, the cross-section will also be a rectangle.
Therefore, the correct answer is B) rectangle.
